So three weeks ago I bought a 2011 2.3 and I'm still getting to grips with the new OS after being raised on Windows. Upgraded the RAM to 8gb of Crucial and yesterday bought a 2011 2.5 as the deal was too good to pass up (9 months old, maic mouse and wireless Apple keyboard for £400) and gives me a degree of future proofing. I'd like to put an SSD in there - not for the boot times as I leave it powered up 24/7 but for faster app loading. They are so much cheaper now but wonder what size I would need for all apps and programmes - I'd use the HDD for music & photos archiving. OCZ Agility or Vertex 120gb is my current thinking but would be happy to hear your thoughts. Ps I plan to trsf the 8gb ram into the 2.5 and sell the 2.3 with the 4gb from the 2.5 Thanks in advance.
